Title: Hydraulic recoil brake for automatic and non-automatic firearms
IPC: F41A25/18
Filed: 1937-10-07
Abstract: 485,524. Ordnance recoil apparatus. SOC. ANON. DES ANCIENS ETABLISSEMENTS HOTCHKISS & CIE. Oct. 7, 1937, No. 27219. Convention date, May 4. [Class 92 (i)] A hydraulic brake for an automatic or non- automatic gun has means for permitting a slight free recoil of the gun, whatever may be the longitudinal position of the gun relatively to the cradle in which the gun is mounted. The rod 3 connected to the gun (not shown) is formed at one end as a cylinder 17 engaging over a tapered core 15, the rod 3 being provided with a ring 14 past which the braking fluid flows during the recoil. The rod 3 slides within a hydraulic cylinder 1 and has a port 12 and a head 9, a piston 5 being mounted freely on the rod 3 between springs 6, 8. When the gun is fired the rod 3 first moves freely (from right to left, as shown), the piston 5 being maintained stationary by the inertia of the fluid, and the spring 8 yielding until the piston is entrained by the shoulder 16 on the rod 3, whereupon the piston displaces the fluid through the fully-open port 12 to effect the braking action. During recoil, the fluid pressure displaces a sleeve valve 20 on the core and a portion of fluid passes through ports 19 into the cylinder 17. When the return-to-battery movement takes place, the valve 20 partially closes the ports 19, under the influence of the spring 23, and thereby brakes the run-out of the gun. The speed of run-out can be regulated by a screw handle 26 on a rod 25, which adjusts the port-carrying member 18 relatively to the core 15 and so controls the opening of the ports 19. A damping spring 27 may be fitted as a buffer for the rod 3.

[Class 100 (i).] A device for registering superposed perforated sheets or webs, applicable to autographic registers and loose-leaf binders, comprises expansible register pins and means for expanding them. In an autographic register in which the superposed webs are fed across a writing table by feed discs 19, Figs. 2 and 4, co-operating with rollers 20, register pins comprising two relatively slidable parts 21, 22 project through apertures in the table and are provided with inclined parts 23a which permit the paper to ride off the pins when the feed movement is resumed. The feed discs 19 have gapped edges, as shown in Fig. 4, so that the feed is intermittent, and expansion of the register pins is arranged to synchronise with the cessation of feed by the provision of a cam 27 on the axle of the discs 19. A spring tends to keep the pins collapsed. In another construction the two halves of the pins are attached to two bars which are urged apart by springs and brought together by the interaction of projections on the bars with cam-slots in lever-actuated members. In the construction shown in Fig. 11, the filing-posts of a loose-leaf file are split into two sections 60, 61 and are expanded by a member 62 which is thrust between them, thus registering the sheets and locking the cover 58 in position. In other constructions, the two halves of the pins are expanded by the rotation of a cam-member between them, or by the action of a wedge.
